Invasive ignorance

It's so hard to get the public to take invasive plants seriously and to avoid using and spreading them (HCN, 4/18/11). I'm disappointed with the scarcity of native plants and the availability of invasives at many nurseries. It's just like grocery stores selling seafood that's on the Red List of Threatened Species. However, there has been an outcry and change on that front, so hopefully the same will happen for invasive plants.
